STAGE 2 BANKROLL MATRIX · 1-2-3-5 · 40U / 10-SHOE
1-2-3-5 Four-Step Ladder — 40-Unit Bankroll & 10-Shoe (720-Hand) Risk-of-Ruin Matrix
Case M208-0 computes the eight-deck 1-2-3-5 Four-Step Ladder (1-2-3-5) across a 40-unit bankroll and a 720-hand (10-shoe) window, where a 100-unit table ceiling and 20-unit stop-loss produce a 94.80% ruin rate while documents an average stake stake-velocity of 1.19x and 10.06u ($1006) in theoretical house-edge toll. Every 8-deck hand remains statistically independent (45.86% Banker, 44.62% Player, 9.52% Tie), meaning progression sizing reshapes session variance without altering the house edge.
